I'm a new RE investor and am putting my team together. I'd welcome any recommendations/suggestions on any General Contractors in the Chicagoland area (Aurora-Naperville IL) for rehab work.

I would recommend Kure Construction in Naperville.  Ryan Kure is the owner and very talented and priced competitively

Hi @Thomas Peddle .  I've recently had luck with Top Notch Remodeling in Plainfield.  I found them on Angie's List, and they did some repair work in one of our rental townhomes a month ago.  The owner, Michael, said they currently work with several investors, and I plan on working with them again for my next project.
